Pepperl+Fuchs’ CAT4AS-Interface magnetic door safety switches feature a coded magnet system with a fixed cable and an industry standard M12 connector, enabling AS-Interface users to safeguard small doors and coverings with a compact solution that mounts in any position, according to the company. With a 36- by 13- by 26.2-mm footprint, model VAA-2E-IER2-S-1M-V1 is the most compact of the two available switches. With a moderately longer 87.5- by 13- by 25-mm housing, model VAA-2E1A-IER1-S-1M-V1 features LED status indicators that provide users with easy-to-read visual diagnostics. Fully encapsulated electronics provide IP67/IP69K protection in ambient temperatures ranging from -20 to 60 degrees C. As with all AS-Interface solutions, power and communication is supplied directly through the AS-Interface network.
